China Executes Mysterious, Secret In-Orbit Satellite Rendezvous

Though the world found out about it through a Russian media outlet, China has been conducting complicated space maneuvers with two of its science satellites over the past few months, directing two of its "Shi Jian" (practice) satellites to rendezvous some 370 miles above the Earth, and possibly even touch. But the fact that China has been so hush-hush about the close encounter has some wondering what it plans to use such technology for. It could be used to build a peaceful space station, but also for interfering with other nations' satellites.

Russian space observer Igor Lissov first noticed the rendezvous buried in publicly available U.S. military data on global satellite positions. In turn it was picked up by Russian media -- and only then by Xinhua, China's state media outlet -- which brought it to the attention of the international community. The data show that between June 12 and August 16 of this year, Chinese satellite SJ-12, a science satellite launched in June, made a series of maneuvers to position itself closer to SJ-06F, an older science satellite launched in October of 2008.
